I've began to notice that i'll shut off my car with a warm engine and run into the store, and when I come out and start it again, it sounds like a very weak start. It only happens when the motor is at normal operating temperatue. It doesn't sound as strong, and it almost seems like it doesnt have enough "juice" to get it going..It hasn't NOT started on me [yet], it just feels like something is become weak on the starter. On a cold start, it will crank fine and feel strong but it does sorta feel like its missing a spark or something..

Difficult to explain, but if anyone understands what I'm talking about, what may be causing this?

 

no ideas?

im having the same problem on my 93 cb7 f22a1 does urs idle really low at first and then come up to normal idle speed ? also, two of my coolant temp sensors are broken so it could possibly be that one of ur coolant temps is going bad and mines still broke so i would check that let me know if u figure anything out .

 

Typically on cars when you have a electrical problem when the engine is hot and not when the engine is cold it is a loose or corroded ground wire someplace. Start by cleaning the battery terminals, and the main ground wire that goes from the battery and connect to the engine or chassis someplace. Shine up all connections with some sandpaper and retighten securely.
